About This Item
The Pentair 3-1/2" Union Nut (98212200Z) is the OEM replacement union nut for the Clean & Clear and Predator cartridge filter series, securing the plumbing union connection at the filter tank.
The union nut threads onto the union body to create a secure, leak-free connection between the filter and the circulation plumbing. When the nut cracks, strips, or no longer seats properly, the joint will weep under system pressure — this direct-fit replacement restores the union to factory specification. Match the part number on your existing nut before ordering.

Pro Tip
When replacing the union nut, inspect the union O-ring at the same time — a compromised O-ring will cause the joint to leak even with a new nut in place. Replace both components together to avoid reopening the connection a second time.
